When you press "F" to generate a fullscreen preview of an image in Lightroom it comes to a black screen with Loading... Now half the time it then gives you the full screen preview. The other half it continues cycling between Lr and the Loading screen with the only way to interrupt the process is to end task the program. After about 2-3 minutes of cycling the program crashes itself if uninterrupted. A Lr process called "Bezel" keeps opening and closing during this time.
My setup is Windows 10 with 4k screen.
Why is this happening Adobe? It isn't only about Mac in the photo industry.
